Security readout for executives and security teams
Plain-English summary
This vulnerability can let an unauthenticated remote attacker obtain user credentials from a Synology C2 Identity Edge Server. The business risk is credential theft from identity infrastructure, not service outage. The public record names fixed versions before 1.76.0-0307 as affected.
Executive priority
Prioritize patching exposed identity edge servers because the impact is direct credential compromise. Treat internet-reachable or broadly reachable deployments as urgent.
Technical view
CVE-2025-14713 is a CWE-749 exposed dangerous method or function issue in Synology C2 Identity Edge Server for DSM. CVSS 3.1 is 7.5, network reachable, low complexity, no privileges, no user interaction, with high confidentiality impact only.
Likely exposure
Exposure is limited to organizations running Synology DSM with the C2 Identity Edge Server package before version 1.76.0-0307, especially if reachable over a network by untrusted users.
Exploitation context
The advisory references PWN2OWN 2025, indicating controlled disclosure context. The provided sources do not show CISA KEV listing or public evidence of active exploitation in the wild.
Researcher notes
Public details are sparse. The available data supports remote unauthenticated credential exposure through an exposed dangerous method/function, but does not describe exploit mechanics, indicators, or vendor-specific detection logic.
Mitigation direction
- Update C2 Identity Edge Server to version 1.76.0-0307 or later.
- Follow Synology advisory guidance for affected DSM deployments.
- Restrict network access to the edge server where operationally possible.
- Assess credential rotation if the affected service was exposed before patching.
Validation and detection
- Inventory DSM systems running C2 Identity Edge Server.
- Confirm installed package version is 1.76.0-0307 or later.
- Identify whether the edge server was reachable from untrusted networks.
- Review identity and service logs for suspicious credential access patterns.
